A method for allocating resources for a scheduling request indicator (SRI) is disclosed. An SRI cycle period for use by user equipment (UE) within a cell is transmitted from a NodeB in a cell to UE within the cell. The NodeB transmits a specific SRI subframe offset and an index value to the particular UE within the cell. The specific SRI subframe offset and the index value enable the UE to determine a unique combination of cyclic shift, RS orthogonal cover, data orthogonal cover, and resource block number for the UE to use as a unique physical resource for an SRI in the physical uplink control channel (PUCCH).
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1 wherein the SRI cycle period extends the unique physical resource to a persistent periodic physical resource.
3. The method of claim 1 wherein the SRI cycle period, the specific SRI subframe offset and the index value are transmitted in UE-specific level three (L3) signaling in a media access control (MAC) protocol data unit (PDU) on a physical downlink shared channel (PDSCH).
4. The method of claim 1, further comprising receiving an SRI from the first UE on the unique physical resource in accordance with the specific SRI subframe offset and the index value.
6. The method of claim 5 wherein the SRI cycle period extends the unique physical resource to a persistent periodic physical resource.
7. The method of claim 5 wherein the SRI cycle period, the specific SRI subframe offset and the index value are received in level three (L3) signaling in a media access control (MAC) protocol data unit (PDU) on a physical downlink shared channel (PDSCH).
8. The method of claim 5, further comprising transmitting an SRI from the first UE on the unique physical resource in accordance with the specific SRI subframe offset and the index value.
10. The apparatus of claim 9, wherein the processor is further operable to determine data is ready for transmission on a physical uplink shared channel (PUSCH), and to instruct the transmitter to transmit an SRI on the unique physical resource on the PUCCH.
11. The apparatus of claim 9 wherein the SRI cycle period extends the unique physical resource to a persistent periodic physical resource.
12. The apparatus of claim 9 wherein the SRI cycle period, the specific SRI subframe offset and the index value are received in level three (L3) signaling in a media access control (MAC) protocol data unit (PDU) on a physical downlink shared channel (PDSCH).
13. The apparatus of claim 9 being a cellular telephone.
